In an effort to tackle the urgent need for sustainable management of coastal areas, the Coastal Autopurification Assessment Technology (CAAT) project in Croatia has developed innovative solutions aimed at measuring the quality and self-purification capacity of coastal waters. The project, which was conducted from 2019 to 2023, employed a combination of oceanographic and atmospheric modelling, research into the flow of pollutants in water bodies, and advanced technological development to achieve its objectives.
Due to its considerable length and the presence of numerous islands, Croatia’s Adriatic coast has been facing significant developmental pressures and the adverse impacts of climate change. In light of these challenges, integrated management and sustainable planning in coastal areas have been identified as critical to safeguarding the environment and the wellbeing of communities in these regions.
One of the primary areas of concern has been the transport of pollution through surface and subsurface runoff, as well as rivers that flow into the Adriatic Sea. This influx of pollutants has led to the eutrophication of coastal waters, resulting in the excessive growth of aquatic plants and algae, ultimately compromising the capacity of the waters to self-cleanse. Consequently, water quality for activities such as swimming, fishing, and other economic pursuits has been severely impacted.
The CAAT project, which brought together a team of 19 researchers from four partner institutions based in Split, Croatia, sought to address these pressing environmental issues. Through extensive research, the development of cutting-edge tools for coastal management, and the creation of a methodology for determining the self-purification capacity of coastal waters, CAAT has made significant strides in this field. Furthermore, the project has focused on the development of technologies such as water quality monitoring systems and sensors, which have been integrated into buoys and remotely operated vehicles for comprehensive testing and measurement.
In addition to its technological advancements, the CAAT project has provided valuable contributions towards achieving European and global sustainability objectives. With its focus on monitoring coastal waters, predicting climate change impacts, and promoting sustainable planning, the project directly aligns with the UN Sustainable Development Goals (SDGs), particularly SDG 9, SDG 11, SDG 12, and SDG 13. Moreover, the project supports the implementation of key EU directives, including the Water Framework Directive and the Marine Strategy Framework Directive, which are aimed at protecting water bodies and marine ecosystems.
In conclusion, the CAAT project in Croatia stands as a testament to the power of technological innovation in addressing complex environmental challenges. By harnessing cutting-edge research and technology, the project has laid the groundwork for sustainable coastal management strategies, contributing to the preservation of marine ecosystems and the promotion of economic and social development in these regions. The impact of the CAAT project is far-reaching and represents a significant step towards creating a more sustainable and resilient blue economy in the EU.
